UNITED STATES PATENT rnrcno JOHN J. COLLINS, OF GRASS VALLEY,CALIFORNIA.

TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 238,763, dated March15, 1881.

Application filed August 9, 1880.

To all whom it may concern:

Be it known that I, JOHN J. Counts, of Grass Valley, in the county ofNevada and State of California, have invented a new and useful TurbineWater-Wheel, of which the following is a specification.

My invention relates to improvements in turbine water-wheels in whichthe axis of revolution may be vertical or horizontal, as desired 5 andthe objects of my improvements are, first, to obtain as great a power aspossible with the minimum of water employed; second, to provide a shoefor the chute for increasing or lessening the flow of water upon thebuckets, and the removing of the same when worn out by friction of thewater or action of sand and gravel upon it. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figurel is a front elevation of the wheel and spout or chute. Fig. 2 is a sideview of wheel; Fig. 3, a bottom view of spout; Fig. 4, a'sectionaldetail view, showing one bucket; Fig. 5, a longitudinal sectional viewof spout or chute.

Similar letters refer to similar parts throughout the several views. I

The outer portion of my wheel A I cast whole with the curved buckets B,and the hub and radial arms or spokes in the center thereof, as shown inFig. 1, with the buckets opening on the periphery of the wheel andhaving their discharge outward at one side only. The construction ofthese buckets is such with reference to their curvatures (3 that thewheel will not only receive the impact of the water, but its weight willalso contribute to greatly (No model.)

accelerate the speed without retarding in the least the outflow of thewater, and especially will this be the case when the axis is horizontal.The water is distributed to the wheel from the outside by means of thechute D. The position of this chute is such with reference to the rim ofthe wheel as to give free play to its motion with as little waste ofwater as possible through the opening necessary for the action of thewheel. The face of the chute is provided with a slotted shoe, E, ofmetal, having beveled edges to fit the beveled sides of the slot in thechute, so that when one shoe is worn by the friction of the water orgravel passing through the slot F another one may be easily substituted;also, shoes having larger or smaller slots can be readily exchanged, soas to direct a larger or smaller stream upon the buckets of the wheelaccording to the head or pressure of the water to be employed.

Having thus described my invention, what I claim,aud desire to secure byLetters Patent, 1s

In combination with a turbine water-wheel having buckets, as shown, thechute D, havin g adjustable and removable slotted shoes E, substantiallyas described, for the purpose set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 9th day of July, 1880.
